Troika

"Troika tells the story of men and women confronting an enigma known as the Matryoshka, a vast alien construct whose periodic appearances have generated terror, wonder, and endless debate. During its third "apparition" in a remote corner of the solar system, a trio of Russian cosmonauts approach this enigma and attempt to penetrate its mysteries. What they discover--and what they endure in the process--forms the centerpiece of an enthralling, constantly surprising narrative. Troika is at once a wholly original account of First Contact and a meditation on time, history, and the essentially fluid nature of identity itself. Suspenseful, erudite, and gracefully written, it is a significant accomplishment in its own right and a welcome addition to a remarkable body of work."--Dust jacket p. [2].
